Abstract

PROBLEM TO BE SOLVED: To simplify the structure of and reduce the costs of truing/dressing devices by their compactification and reduction of weight. SOLUTION: A truing/dressing device 1 for super-abrasive grain wheels permits a dressing wheel 3 having such a shape as causes a difference in speed between inner and outer regions on the dressing surface, to be entrained or rotated by a rotating super-abrasive grain wheel while fulfilling equal-speed conditions or to true or dress the super-abrasive grain wheel. The dressing wheel 3 of the truing/dressing device 1 is provided with follow-up rotation means for causing it to be rotated via contact with the super-abrasive grain wheel. The interface between the super-abrasive grain wheel and the dressing wheel 3 in contact with each other thus has an appropriately located equal-speed region wherein they have the same speed, and the equal-speed region is movable appropriately over a wide radial range of the dressing wheel 3.

2. Description of the Related Art A truing and dressing method for a super-abrasive wheel such as a diamond wheel among grinding wheels includes a brake truer, a forced drive cup truer, and the like.
A luer system such as a cup type brake lure and a mild steel grinding method are known. The present inventor has proposed that
A truing and dressing method having an efficiency of 10 times or more and a high-precision run-out capability has been studied, and a method and apparatus disclosed in Japanese Patent No. 0832811 (Japanese Patent Publication No. 4-13099) have been proposed. In recent years, the “constant velocity condition” has been recognized. The means for satisfying the "constant velocity condition" is that, when dressing by contacting the side surface of the dressing grindstone which rotates the superabrasive wheel, the peripheral speed of the superabrasive grains on the outer peripheral surface of the superabrasive wheel is changed to the side surface of the dressing grindstone. Is forcedly rotated so as to be substantially equal to the peripheral speed of the intermediate portion.

The present inventors have studied a method and apparatus for obtaining a simpler and better truing and dressing effect under the above "constant velocity condition". In the conventional apparatus, since the dressing apparatus side is a forced drive system, the "constant velocity condition" is satisfied only within a range of only a few millimeters on the dressing grindstone. The necessity of having a drive source motor for forced drive inside the device makes the device itself expensive. In addition, the motor of the drive source significantly increases the height of the device, which is a factor that makes the device heavy. Further, since the motor of the drive source generates heat, it is not preferable in the field of precision machining which does not like dimensional change. Therefore, the present inventor has studied to provide a truing and dressing device that is reduced in size and weight, simplified and provided at a low price.

1 and 2 show an embodiment of the present invention, and are plan views of a truing and dressing apparatus 1 for a superabrasive wheel according to the present invention, and FIG. 2 is a longitudinal sectional view at the center. FIG. 3 is a perspective view showing a dressing operation of the superabrasive wheel 2 by the truing and dressing apparatus 1 of another embodiment. The truing and dressing apparatus 1 is used for shaping or dressing the processing surface of the superabrasive wheel 2. One of the features of the truing and dressing apparatus 1 for a superabrasive wheel of the present invention shown in the embodiment is that the outer peripheral side surface 3a and the inner peripheral side surface 3b of the annular dress grindstone 3 in the radial direction are provided.
In this case, the rotating tires 4 and 5 are arranged as the rotating means. It is preferable that these co-rotating tires 4 and 5 project slightly toward the superabrasive wheel 2 from the surface (dresser working surface) where the dressing grindstone and the superabrasive wheel 2 are in contact with each other, but at the same position as shown in the figure. Even if they are arranged in such a manner, they rotate together. The outer peripheral side swivel tire 4 has a fastening band 11
To prevent it from coming off by tightening from the outer circumference.

As is apparent from FIG. 2, the annular dressing grindstone 3 has a face plate 6 holding the dressing grindstone 3 and a fixing plate 7 fixedly held by a main body block 8 via a bearing 9 so as to be freely rotatable. Therefore, the circular rotation of the dress whetstone 3 is free. In addition to the fastening by the fastening band 11, various means for preventing the movement of the tire 4 on the outer peripheral side can be considered. For example, as shown in FIG. 3, a rotating tire 4 having a width substantially equal to the thickness of the dressing grindstone 3 is fitted. In addition, the outer shape of the ring-shaped dressing grindstone 3 is tapered at the bottom to prevent the tire 4 from falling along with it.

As another example of the entraining means, a cut groove which is slightly inclined in the radial direction and in the traveling direction is provided in a part of the ring-shaped dressing grindstone 3 and an elastic strip is fitted therein. Thereby, the super-abrasive wheel 2 and the dressing grindstone 3 have a constant velocity region where they have the same speed where they come into contact with each other. Further, as shown in FIG. 5, a material in which a granular elastic member 12 is mixed and arranged so as to be exposed on the dresser working surface in the pore portion of the dressing grindstone 3 can also be a rotating means.

As a result, the pass was completed in only 60 passes to reach the shake amount of 0.8 μm (see FIG. 4). If a conventional brake tool is used and the cut is made 5 μm in the same way, the shake amount can be obtained only up to 1.8 μm in 1500 times. Excellent results were obtained with the method and apparatus of the present invention. FIG. 4 is a chart showing the flatness measurement result of the dressing result on the surface of the superabrasive wheel by the truing dressing apparatus of the present invention.

According to the present invention, the truing and dressing device can be reduced in weight, size and cost.
In addition, truing and dressing can be performed in a low speed range, and the work is safe and easy. Since a motor serving as a heat source is not used, there is no dimensional change due to thermal displacement, and it is suitable for high precision machining. Since the dressing grindstone does not rotate at high speed, the dynamic balance of the entire apparatus has almost no effect. From this point, the apparatus can be provided at low cost.
